Abstract
A Cascaded H-Bridge Multilevel Inverter is a power electronic converter built to synthesize a desired ac voltage from several levels of dc voltages with better harmonic spectrum. This paper analyzes the performance of a cascaded H-Bridge seven level inverter topology employing multicarrier pulse width modulation technique which magnifies the fundamental output voltage with reduction in total harmonic distortion to 24.64% when compared to the five level inverter. The inverter is capable of producing seven levels of output-voltage levels from the dc supply voltage. It can also be easily extended to any number of phases or levels. The performance has been studied by the MATLAB/Simulink. The output shows better performance results.
